Patched "Pragmata Pro Mono" font (version 0.828) used to work pretty well on Windows until recently.

Here is what I do:

FontForge-2020-03-14-67687b0-x86_64.AppImage -script ${dir}/font-patcher --careful --complete --mono --windows -out ${home}/work_done ${home}/work/PragmataPro_Mono_${variant}_${ver}.ttf

After commit 59c45ba Windows 10 fails to detect patched font as monospaced and fc-scan on Linux does not show spacing: 100(i)(s) any more. Placing remove_glyph_neg_bearings back before set_glyph_width_mono fixes the problem.

I am not really sure this is proper fix (since I am not familiar with original issue "Remove negative bearings on 2048-em glyphs"...
